A center hole I2 is punched out of the 45 laminated fabric bufing ring, a pair of opposed body member Il to provide a means whereby the disks which constitute a support for the buing body member may be mounted on the hub or shaft ring having a peripheral groove receiving the of a bufnng or polishing lathe. This center hole inner edge of the bufllng ring, each of the disks I2 is provided with a slight flange I3 to insure having a centrally located shaft receiving hub, a proper seating of the body member on the hub. web member surrounding said hub, a shoulder Six or more radial slots I4, are also punched at the outer periphery of the web, a narrow anout of the body member I I. A shoulder I5 is then nular flange extending beyond the shoulder in a drawn.
